Answer:
Angle 1 is 62
Angle 2 is 45
Angle 3 is 24
Step-by-step explanation: from
To get angle 1 you subtract 118 from 180 (180-118) and get 62
For angle 2 you subtract 62 and 73 from 180 (180-62-73) and get 45
For angle 3 you first subtract 73 from 180 (180-73) and get 107 then subtract 107 and 49 from 180 (180-107-49) and get 24
You subtract everything from 180 because with straight lines they are equal to 180 degrees and triangles are also equal to 180 degrees
